MOVING-PICTURE MACHINE.

Specification of Letters Patent.

Patented'Oct. 19, 1909.

T 0 all whom it may concern:

Be it known that I, Baarox A. Pnocron, a citizen of the United States,and resident of New York city, in the county of New York and State ofNew York, have invented a certain new and useful Improvement inlrloving-Picture Machines, of which the following is a specification.

The present invention relates 'to moving picture machines, moreespecially the filmmoving and guiding means, and has for its primaryobject the simplification of .the mechanism and the improvement of theoperation therefor.

The preferred form of the invention is illustrated inthe accompanyingdrawing, forming part hereof, in which Figure 1 is av verticallongitudinal sectional view on the plane-w ar ofFig. 2. showing thelens-holder in dotted lines, and the frame a broken away in order toshow more clearly certain working parts behind the same; Fig. 2 is afront elevation of the mechanism shown in 1; Fig. 3 is a plan,sectional, view on the plane 33 of Fig. 2, but omits certain parts; andFig. 4 is aplan view, partly in section, to illustrate the action ofcertain parts.

In the drawing, the reference symbol .a designates an upright plate,which is secured in any suitable manner to a base b, and which isprovided with the picture framing opening 0 and with a slot 03. Abovethe slot (Z is a tongue 6, bent forward and then backward as shown inFig. 1, by means of which the film Fis guided toward the film-moverhereinafter described. The plate a is provided with a pair ofparallel'arms f The lens holder 9 is formed of a strip of sheet metalbent into circular form in the middle portion thereof and having itsends bent int-o hooks 72. which embrace and slide upon the guide-arms faforesaid, thus providing means for the adjustment of. the focusinglenses (not shown). r

The referenced marks aclamping plate provided with a framing opening iswhich registers with the opening 0 aforesaid. The plate 71 1s providedwith parallel lugs Z, be-

tween which the film F moves, which lugs pass through v perforations orslots p in the plate a, and with the curved ears mwhich pass through theholes o-in the arms f or in metal connecting said arms with the plate a.

1* whose end is fastened to the carrier 2, or to .a lug s thereon, whichspring 1" 1s tensioned to withdraw the film-moving finger g from itsoperative position, shown in full lines in Fig. l, to its normal orinoperative position, shown in dotted lines in Fig. 1. The filmmover isprotruded to cause it to engage with the. perforations 'j in the film Fas shown, by means of a cam 'w which is fixed to aside-plate a and thiscam is so-located that the film-moving finger g snaps inwardly ofthe-carrier t at right angles, or thereabouts, to the plane of the filmF, as the said finger slips off the end of the said cam w.

The carrier 6 is fast on the shaft 20 which is cause the carrier t torevolve in the direction of the arrow 7 thereon, thus carrying thefinger g aroundin a path which, for the most part, lies wholly withinthe periphery of the carrier t, in the particular instance illustrated,but which path, at the moment when the cam 'w protrudes the finger g tocause/it to engage with and move the film F, passes beyond the saidperiphery and so remains until the finger g snaps off the cam, duringwhich time the finger moves the film'downward to bring the succeedingpicture thereon opposite the framing opening a. The finger 9 will alsomove the film upward if the crank-shaft y be turned the other way, sincethe block 8 where the spring 1' is secured to the carrier is soplacedwith relation to the end'of the cam to that the end 9 is cammedoff by the cam w and into engagement with the film. The carrier t andthe side-plate a i clearly in Fig. 4, the end of the plate being in thearc of a circle concentric with the disk of the carrier 25 and of thesame radius. The side plate a ismade fast to the plate, a,prefspring-retracted film-mover mounted thereon, and a cam forprotruding said filmmover. I

2. In a moving-picture machine, the combination of a rotary carrier, aspring-retracted film-mover mounted thereon, said mover being acontinuation of the said spring, and a cam for protruding saidfilmmove-r.

3. In a moving-picture machine, the combination of a rotary carrierprovided with a lug on one'face thereof, a spring fast to said lug andhaving its free end bent at an angle tothe bodythereof to form afilm-mover, and a cam for forcing said finger outward relatively to saidcarrier.

4. In a moving-picture machine, a filmguide consisting of a circularcarrier and a round-end side-plate coacting with said film near itsedges. v
